The purpose of the present study was to examine the relation- ships among critical sport psychosocial perceptions of fathers (N=84), mothers (N=84), and daughters (N=84) in the same family (N=252). Athlete participants were young female soccer player

Porous anodic layers were grown on aluminium alloys under different anodizing conditions. Positron annihilation energy spectra were measured as a function of the positron energy. Ortho-positronium formation in the porous layer was detected. The posit

It is shown that /sup 12/B nuclei produced in the /sup 12 /C(/b n/ oarr ,/b p/)/sup 12/B reaction are polarized. The polarization of /sup 12/B is measured through its beta-decay asymmetry. The analyzing `efficiency' epsiv =/b P//sub N///b P //sub n/

A new fast gas-filled multiwire counter of high efficiency has been developed for experiments based on the observation of low energy X-rays. A time resolution down to 30 ns (fwhm) has been achieved at 2.3 keV. Detector and electronic designs are deta

A novel method involving the Zeeman effect is used to directly measure the alignment correlation term in the beta decay of /sup 12/B, /sup 12/B rarr beta +/sup 12/C. The approach is reminiscent of the direct measurements of the lepton g-factor anomal

We have developed and successfully tested a new type of time-reference signal for experiments using the pulsed structure of cyclotron beams. This was achieved by coupling the usual rf signal to typical scintillator time pickoff assembly. This techniq
