Schematic representation of and in Eq. (6) . The solid horizontal line is the energy and the dashed segment is the bound state energy of . Note that by increasing or decreasing the magnetic field, the dissociation threshold at (horizontal dotted line) is shifted up and down. In the figure, .

Plot of the effective interaction in Eq. (19) . By varying , can take any value in the range . This plot corresponds to the choice in Eq. (14) .

Graphical solution [see Eq. (36) ] of . The thin solid black lines represent and the thick grey lines represent for two different values of . The solutions are the values where the curves intersect (denoted by black dots). Depending on the value of (the onset of the hyperbola on the axis), there are either two solutions or one; two solutions if and one solution otherwise. In the figure, we have plotted the solutions for two such values of .
