Abstract

The (

p, n

) thresholds for the formation of

{}^{20}{Na}

,

{}^{28}P

,

{}^{32}{Cl}

, and

{}^{36}K

from targets of

{}^{20}{Ne}

,

{}^{28}{Si}

,

{}^{32}S

, and

{}^{36}{Ar}

, respectively, have been measured relative to the

{}^{24}{Mg} (p, n) {}^{24}{Al}

threshold by detecting

β

rays from these short-lived activities. Half-lives were determined by multiscaling techniques. The resulting (

p, n

) thresholds (in keV), half-lives (in msec) are as follows:

{}^{20}{Na}

(15419±6, 442±5);

{}^{28}P

(15 666±6, 266±4);

{}^{32}{Cl}

(13 902±9 and 13 978±16, 281±8);

{}^{36}K

(13 976±8, 336±4). The half-life of

{}^{24}{Al}

was measured as 2.054±0.009 sec.
