Lawrencium has been synthesized only in very minute quantities. It was first synthesized by irradiating a mixture of californium isotopes with boron ions:<br /> <img src="http://www.chemicalbook.com/NewsImg/2018-08-17/20188171531165116.jpg" /><br /> The isotope obtained this way has a half-life of about 4.2 seconds and is an alpha emitter.<br /> Lawrencium-256 ( ~35 seconds) is prepared by bombarding americium-243 with oxygen-18:<br /> <img src="http://www.chemicalbook.com/NewsImg/2018-08-17/20188171531294633.jpg" /><br /> All lawrencium isotopes of masses 255 to 260 have been synthesized by bombardment of transuranium elements with heavy ions.
