The work contains numerical and approximate analytical (BETA-model) equations solutions for energies and matrix elements of the b-decay of these states. The special attention is paid for the description of the new type of giant isobaric state � the Gamov-Teller resonance which was discovered recently in the Michigan and Indiana Universities, USA. The possibility of Gamov-Teller resonance and nuclei ground states description in the theory of Wigner supermultiplets is analysed. It is shown that the SU (4) description improves in heavy nuclei as A and N � Z grow. The role of the isobaric collective states in b-decay and delayed neutron emission from nuclei far from the b-stability line is discussed. 袜 铖眍忮 蝈铕梃 觐礤黜 翦痨�-耔耱屐 耱痤栩�� 蝈铕�� 桤钺囵梓羼觇� 觐腚尻蜩忭 1+-耦耱��龛� 耵屦梓羼觇� �溴�. 务钺铄 戾耱� 铗忮溴眍 铒桉囗棹 眍忸泐 蜩镟 汨汔眚耜钽� 桤钺囵梓羼觐泐 疱珙磬眈� � 汔祛�-蝈腚屦钼耜钽� 疱珙磬眈�, 镳��怆屙桢 觐蝾痤泐 � 疱嚓鲨�� 镥疱玎��潢� 镱潋忮疰溴眍 礤溧忭� 磬 耧屦桁屙蜞� � 软滂囗耜铎 � 惕麒汔眈觐� 箜桠屦耔蝈蜞� 沿�. 理嚯桤桊箦蝰� 忸珈铈眍耱� 铒桉囗�� 汔祛�-蝈腚屦钼耜钽� 疱珙磬眈� � 铖眍忭 耦耱��龛� �溴� � 聃屐� 忤沩屦钼耜铋 耔祆弪痂� 磬 徉珏 SU (4)-沭箫稃. 项赅玎眍, 黩� 蜞觐� 铒桉囗桢 箅篦弪�� � 痤耱铎 N � Z � 疣轭礤 ��驽臌� �溴�. 泥� 钺珙� 耧屦桁屙蜞朦睇� 桉耠邃钼囗栝 镱 汔祛�-蝈腚屦钼耜铎� 疱珙磬眈� � 觐腚尻蜩忭 桤钺囵梓羼觇� 1+ -耦耱��龛��. 朽琊噌铗囗� 戾蝾滂赅 疣聍弪� 疋铋耱� �溴�, 溧脲觇� 铗 腓龛� b-耱噌桦铖蜩, 铖眍忄眄�� 磬 蝈铕梃 桤钺囵梓羼觇� 耦耱��龛�, 镳桁屙屙桢 觐蝾痤� 桦膻耱痂痼弪�� ��漕� 镳桁屦钼.
