Reakcii skalyvaniya
- yadernye reakcii, v k-ryh legkaya chastica vysokoi energii, stalkivayas' s tyazhelym yadrom, vybivaet iz nego sravnitel'no legkii oskolok (yadro legkogo elementa). V yadernoi astrofizike R.s. privlekayutsya dlya ob'yasneniya obrazovaniya legkih elementov: D, Li, Be, B, a takzhe anomalii v him. sostave magnitynh zvezd. Pri etom predpolagaetsya, chto R.s. vyzyvayutsya protonami, uskorennymi v peremennyh el.-magn. polyah vo vnesh. sloyah zvezd. Protony s energiyami vyshe 20 MeV mogut vyzyvat' R.s. vseh bez isklyucheniya tyazhelyh yader, no naibol'shee znachenie imeyut R.s. s uchastiem samyh rasprostranennyh yader - yader atomov C, N, O, Fe. Vysokoe soderzhanie Li v molodyh zvezdah (v osobennosti tipa T Tel'ca) mozhet ob'yasnyat'sya R.s. na rannih stadiyah evolyucii zvezd. Stol' zhe vysokoe soderzhanie Li i preobladanie nechetnyh izotopov Li i B v veshestve Zemli i meteoritov mogut byt' ob'yasneny R.s. v processe obrazovaniya Solnechnoi sistemy, kogda uskorenie chastic proishodilo v teh zhe magn. polyah, kkie obespechivali peredachu vrashatel'nogo momenta ot molodogo Solnca rozhdayushimsya planetam (sm. Proishozhdenie Solnechnoi sistemy, Rasprostranennost' elementov).(D.A. Frank-Kameneckii)
