我们库仑爆炸氩和氖二聚体，三聚体，和四聚体的多重电离在超短800 nm的激光脉冲。通过同时测量单电荷离子的所有动量矢量，我们确定了二聚体、三聚体和四聚体的基态核波函数。此外，我们通过经典的数值模拟，在位置空间中检索的三聚体的键角。对于氩和氖三聚体，我们发现了一个接近等边三角形的结构。在等边三角形周围的分布宽度，氖比氩宽得多。
We Coulomb explode argon and neon dimers, trimers, and tetramers by multiple ionization in an ultrashort 800 nm laser pulse. By measuring all momentum vectors of the singly charged ions in coincidence, we determine the ground state nuclear wave function of the dimer, trimer, and tetramer. Furthermore we retrieve the bond angles of the trimer in position space by applying a classical numerical simulation. For the argon and neon trimer, we find a structure close to the equilateral triangle. The width of the distribution around the equilateral triangle is considerably wider for neon than for argon.
