The problem of the bimolecular rate constant, alpha , for the mutual charge neutralization reaction (ion-ion recombination) for ions formed by the vacuum ultraviolet photolysis of nitric oxide is considered. The pressure dependence of alpha over a pressure range of 10 to 600 torr for mixtures of a few hundred microns of NO with He, Ar, Kr, Xe, H/sub 2/, D/sub 2/, and N/sub 2/ was measured. From the low-pressure limit of alpha , the rate constant for charge neutralization in the absence of a third body was found to be k/sub o/ = 2.1 plus or minus 0.4 x 10/sup -7/ cm/sup 3// sec. The high-pressure limit of alpha was estimated to be 2.0 plus or minus 0.5 x 10/sup -6/ cm/sup 3//sec. The third-body efficiencies for promoting the charge-neutralization reaction were measured. The results, relative to He as the third-body gas, are H/sub 2/= 1.4 plus or minus 0.4, D/sub 2/= 1.5 plus or minus 0.4, Ar =3.6 plus or minus 0.8, Kr =4.3 plus or min11.0, N/sub 2/ = 5.2 plus or minus 1.1, and Xe = 6.8 plus or minus 1.5. The average ionic mobility in the gas mixtures is estimated, and the mobilities indicate that …

The major problem to be investigated consists of four phases: 1) the investigation of the relationship of sociempathic ability to self concept, sociometric status, mental ability, student teaching, and teaching effectiveness of elementary and secondary student teachers, and the relationship between sociometric status and self concept; 2) an investigation of the relationship of self concept and sociometric status to the teaching effectiveness of elementary and secondary student teachers; 3) a comparison of elementary and secondary student teachers on the strength of the relationships mentioned above, and on mean scores in self concept, sociempathic ability and mental ability; and 4) an investigation to determine if differences in self concept ratings exist among subject major groups of secondary student teachers, and to determine if there are differences between the sexes with regard to sociempathic ability.

The purpose of the present study is fourfold: (1) to investigate the predicted relationships between self-acceptance and acceptance of others, (2) to investigate self-acceptance, acceptance of others, and their interrelationship with acceptance by others, (3) to investigate the patterns of interrelationship between self-acceptance, acceptance of others, actual acceptability to others, and predicted acceptability to others, and (4) to investigate an hypothesized curvilinear relationship between self-acceptance and acceptance of others.

It is the purpose of this study to compare the readiness and achievement of older and younger first grade students. Other purposes of the study involved a comparison of girls and boys in the first grade as to their readiness and achievement.

This study is an attempt to ascertain if there is a relationship between academic achievement, I. Q. and social maturity in mentally retarded children in an institutional setting.

The present study was designed to investigate whether or not retardates' level of aspiration and subsequent performance are significantly affected by the presence and observation of a peer group.

This study was designed to determine the effect upon reading achievement of students who choose an elective course in either life science, creative writing, or accelerated reading in lieu of regular reading classes.

The purpose of this study is twofold. First, it is to obtain further evidence of the concurrent validity of the AC Test of Creative Ability. Further, and more specifically, it is concerned with the generalization of previously indicated validity of the AC Test to a college situation.

The problem of this study was to ascertain the relationship between secondary school principals' evaluation of professional behavior patterns of secondary teachers and these teachers' self-descriptions.

In Part One they formulate in a general way the problem of analyzing and evaluating the aberrations of quadrupole magnet beam systems, and of characterizing the shapes and other properties of the beam envelopes in the neighborhood of foci. They consider all aberrations, including those due to misalignments and faulty construction, through third order in small parameters, for quadrupole beam systems. One result of this study is the development of analytic and numerical techniques for treating these aberrations, yielding useful expressions for the comparison of the aberrations of different beam systems. A second result of this study is a comprehensive digital computer program that determines the magnitude and nature of the aberrations of such beam systems. The code, using linear programming techniques, will adjust the parameters of a beam system to obtain specified optical properties and to reduce the magnitude of aberrations that limit the performance of that system. They examine numerically, in detail, the aberrations of two typical beam systems. In Part Two, they examine the problem of extracting the proton beam from a synchrotron of 'H' type magnet construction. They describe the optical studies that resulted in the design of an external beam from the Bevatron that is …
